124 inches of a frame is the required amount. 31 times 4 is 124.
Answer:
1/(x^3)
Step-by-step explanation:
The applicable rule is x^m / x^n = x^(m-n), so here
x^4 / x^7 = x^(4-7) = x^(-3)
next applicable rule, x^(-n) = 1/(x^n) OR (1/x)^n (they are equivalent), so here
x^(-3) = (1/x)^3 OR 1/(x^3), which ever looks better to you and your instructor, likely the second
Answer:
2nd option is the right answer
Jason is buying 2 hats and 3 scarves for each of his 4 children
so he is actually buying 8 hats and 12 scarves.
a hat costs 8.50 and a scarf costs 5.50
so you put it into a equation
8.50(h)+5.50(s) = P h = hat, s = scarf, P = pay
8.50(8)+5.50(12) = P
68 + 66 = P
P = 134
hope this helps
